1 Annex 8.5 Hazardous Materials Decontamination Operating Procedures for Primary and Community Care Settings Version Version 1 Review date 23 rd September 2015 Author Pete Old Health Emergency Management Specialist 1

2 Introduction 1 This guidance document is aimed at preparing primary and community-based health facilities to be able to manage the consequences of a hazardous incident occurring somewhere else. Whilst this document uses the term hazardous incident which is interpreted as from an accidental source it is also applicable to contamination from a deliberate source termed as CBR(N)E (Chemical, Biological Radiological (Nuclear) and Explosive incidents). The NHS is expected to care for patients, but also be aware of the safety risk to staff and patients from secondary contamination as a result of people selfpresenting at their facility seeking assistance. Primary and Community Care facilities include GP practices, pharmacies, dentists, opticians, health clinics, walk in centres, minor injury units and community hospitals without minor injury units. Aim of this guidance To enable primary and community care practitioners to adopt simple planning and response principles that would enable care to be provided to people self presenting as a consequence of a hazardous incident, at the same time protecting staff, patients and property from secondary contamination. To support primary and community care practitioners in planning for a hazardous incident by providing a resource pack, including; o Action cards for front line responding staff; o Guidance for primary and community care leads to follow in the preparation and response to an incident. To promote an understanding of the implications of a hazardous incident on the business continuity of the primary or community care facility. Background Experience from incidents such as the Tokyo sarin attacks in 1994 and 1995, and the London bombings of 2005, demonstrate that large numbers of people will self evacuate, if they can, and leave the scene without first coming into contact with the responding emergency services. Potentially later once symptoms have developed or due to media coverage become anxious and self present to primary or community care facilities in search of treatment or advice. Of course on a day to day basis accidents happen that involve chemicals and people with chemicals on their skin or clothing may present at any primary or community health care facility seeking advice. The guidance contained in this document is relevant to both deliberate and accidental contamination of people who present to health care professionals. As it is likely that in a major incident involving chemicals the emergency services will be fully committed primary and community care facilities should plan for unsupported management of self presenters in the initial stages, obtain specialist advice and provide information to keep people calm whilst taking action to remove or neutralise as much of the chemical as possible and treating the patients symptoms. 2

7 OVERVIEW Aim For primary and community care facilities to be able to take necessary actions to prepare themselves for the consequences on an incident involving hazardous chemicals. Objectives To care for self presenters,; to maintain staff safety; to recognise the role of front line first receivers to maintain essential services; to return to normal business as soon as possible Why Prepare Following an incident where people have been exposed to hazardous materials many worried well and potentially contaminated people will self present at primary and community care facilities without having been assessed or treated by emergency services at the scene. Evidence shows that frontline healthcare staff can suffer secondary contamination if they are not prepared for such incidents. 3 PRINCIPLES OF PREPAREDNESS FOR PRIMARY AND COMMUNITY CARE Recognise unusual circumstances and be aware of the risks Manage the incident and limit the spread of contamination Give priority to minimising exposure and safety risks to staff Provide care and information to patients Communicate and obtain guidance from external agencies and other primary care facilities Maintain business continuity and recover to normal business as early as possible KEY PREPARATION ACTIONS 1 ST PREPARE THE BUILDING How do you lock down your facility Produce a lock-down procedure with the reception area and train staff. to prevent people entering? How to isolate people and limit the spread of contamination? Identify an isolation area. Have signage ready. Train staff in isolation procedures 2 nd PREPARE MANAGEMENT AND LOGISTICS How are you alerted to the risk? Coordinate with NHS and health partners. Make sure that systems to alert you are correct and tested regularly How to assess the risks to your staff Train staff to understand the range of risks. Produce a quick reference checklist and facility? Further support from PHE or Emergency Planning Officer How to manage the incident Identify who will be in charge. Produce an action card for the incident manager. Train staff and conduct exercises. How to cascade alerts and Produce a contact list for external agencies and primary care organisations. Test information? alerts regularly. Who to contact for advice and Produce a contact list of who can provide you with advice and guidance. Ensure that guidance? you know how to contact your local PHE office where further advice will be given at the time. How to continue to continue Maintain current and tested business continuity plan business as normal? 3 rd PREPARE STAFF How to prepare front line staff to be aware of & recognise risks How to prepare back-office staff to support front line staff and manage these incidents How to minimise exposure and keep staff safe How to care for self presenters What equipment to have ready Train staff in the STEP safety code previously described Train staff in how to support front line staff Train frontline staff in infection control procedures and to minimise contamination risks Produce procedure for frontline staff to first assess patients; then to advise on what information to give and what decontamination/treatment to provide if advised to do so. Ensure staff are aware that expert advice will be provided about when and how its safe for patients and staff to leave. Consider preparation of a response box to be available at reception with suitable personal protection equipment and selected items (forms etc). Ensure that PPE is reviewed and updated regularly. Provide action cards to staff. Test internal alerting six monthly (recommended). Consider conducting exercises with local partners. 3 Wheeler, H Chemical Terrorism: The Japan experience and lessons learnt. Chemical Incident Report. Issue 14 CHAPD 7

8 Primary or Community Care Lead Action Card Preparation for incidents involving hazardous materials 4 You need to be aware that; EXTERNAL ACTIONS INCIDENT OCCURS INTERNAL ACTIONS Ambulance service/public health England: Identify hazardous substance Assess impact on health PHE Formulate specific guidance for primary and community care Issue guidance to GPs, Walk in centres etc. via /fax SEE NOTE 1 STEP 1 Manage using normal One Casualty protocols STEP 2 Two casualties with Manage with caution and similar symptoms and no consider risk to staff and apparent cause others STEP 3 Manage as an incident Three or more casualties involving hazardous with similar symptoms materials: risk assess and no apparent cause before intervening Receive telephone call from receptionist/member of staff alerting you to problem GP, Walk In Centre etc. Are we likely to be involved? NO Monitor Situation YES Actions to prepare for self presenters Before self presenters arrive 1. consider locking down the facility, and prepare staff 2. Postion signing outside of building requesting presenting patients to contact reception and remain outside the building 3. Inform the Senior Manager On Call of the situation If self presenters have already arrived 1. If contaminated patients have already arrived then the receptionist or person in first contact should now be considered as contaminated and must not leave the dirty contaminated area. 2. Lockdown the building; establish clean and dirty areas within the building; put up signage outside, keep patients and staff informed. 3. Cancel non-urgent appointments and undertake any other business continuity actions. 4. Have you received guidance? ((see Note 1) NO YES Self Presenters Arrive NO YES Ensure you: 1. Call 999 if there is a medical emergency 2. Contact PHE 24 hour number Manage self presenters according to specific guidance received from PHE or if applicable follow first responder decontamination guidance in section 6 Establish communications with Public health and PHE for further information Protect yourself with PPE, cleaning, lockdown etc. according to general guidance (see Note 2) Keep accurate details of patients seen Your response will be supported by the Emergency Services following your call to them SEE NOTE 2 8

9 Notes Preparation for incidents involving hazardous materials 5 NOTE 1 Whenever an incident resulting in contamination (or possible contamination) of people, animals, air water, food etc. is known to have taken place, identifications of the substance is a priority. Several agencies can be involved in making this identification and in assessing the impact on human life and the environment, once the substance is known. Public health England (PHE) will assess the impact on Public Health and will provide advice to the affected premises as well as advice and communication to the local authority and local NHS. If the incident may have implications for the community, information will be developed by PHE regarding the substance (if known) and the risks and action to be taken in the event of self-presenters. This will be sent out as quickly as possible to primary and community care providers. The message will be sent widely, not just to premises in the immediate vicinity because contaminated people may have travelled some distance before deciding to seek help. Self- presenters should be managed according to the instruction in the guidance. NOTE 2 Protecting yourself, other patients/staff and premises The aim is to minimise the contact that the potentially contaminated patient has with other people and parts of your premises. Immediate action isolate the person in a separate room if not contaminated with a substance with a strong smell i.e. petrol preferably somewhere without soft furnishing. DO NOT TOUCH THEM Cordon off the part of the premises they have walked through and anything they have touched. If necessary lock the doors and put notices up outside the premises to redirect other patients away from the area. Those involved in patient contact should wear the following Personal Protective Equipment if available; o Apron or waterproof gown o Gloves o Mask (highest specification available i.e. FFP3 PPE should be disposed of as contaminated waste Re-route other patients away from the area Staff and patients who have come into contact should be reassured and asked to stay on the premises until further information is received about the contaminant. 9

10 Preparation for Incidents involving Hazardous Materials 6 PATIENTS Recovery Information 1. Ensure detailed records of all patients involved within your premises have been taken and are kept. Include name, DOB, home address, contact telephone number, GP, symptoms and any action taken see Patient Contact Template 2. Keep in contact with the Ambulance Service and PHE for updates and further advice about sending patients home or moving patients for further care. 3 Continuing sensitive and timely communications with your patients and the public will help ensure their ongoing cooperation and provide reassurance. Explain the current situation and your ongoing plans Set out options for the different categories of patients (I.e. exposed patients, worried well, urgent regular cases and non urgent cases) Consider introducing clinical assessment and triage at reception Use sign posting at the front entrance and within the building Create a temporary answer phone message for the recovery phase. 4. Consider the welfare of your patients Provide hydration and refreshments if at all possible Prove clean clothing and blankets. Dirty clothing should be sealed in plastic bags if advised by PHE Ensure they have access to regular medications they may be on Ensure access to telephones for the purpose of contacting friends and relatives and making arrangements for dependants. STAFF Recovery Information 1. Consider staff welfare Provide refreshments and regular breaks Provide clean clothing and blankets Consider arrangements for transporting staff home when its safe to do so Ensuring they have access to any medication they may be on Ensure access to telephones for the purpose of contacting friends and relatives and making arrangements for dependants. Consider the potential need for ongoing psychological support for staff involved in the incident. 2. Maintain service continuity Review workforce plans including the availability of staff/critical resources and staffing arrangements for the next working days. Consider when normal services can continue and how long contaminated staff might need to be off work. Refer to your service business continuity plan and liaise with the senior manager on call. Review any missed or cancelled appointments and waiting lists for services and manage any backlog Prioritise your essential services and urgent patients until normal service can resume. Afterwards conduct a review of the incident and response plans and update as necessary. BUILDINGS Post Incident Information Take advice from PHE, local authority Environmental Health Department or Environment Agency whichever has the lead. The contaminated area should not be reopened until advice has been taken. If required due to complex or gross contamination the Government Decontamination Service will be contacted for advice by the on call managers working in liaison with estates. Any contaminated clothing and washing products or use PPE should be double bagged and stored in the dirty zone within the isolation area. Advice on how to deal with, or dispose of the contaminated clothing should be taken as it may be required as evidence by the police or health and Safety Executive. Significant contamination incidents are initially likely to be treated as crime scenes for the preservation of 10

11 evidence relevant to subsequent investigations. Therefore, no property or documents should be discarded. Take advice about potential contamination of the water supply from PHE or water supplier if felt it has been compromised in some way. First Responder Decontamination Guidelines 7 Purpose of these guidelines These guidelines are provided to advise Minor Injury Unit staff or staff of other Primary care facilities of how to decontaminate casualties presenting to them having a history of being contaminated. Patients may become exposed to a chemical substance in several ways including, but not limited to: exposure incurred during a household accident exposure incurred during an occupational accident exposure incurred during the deployment of a chemical compound as a weapon or terrorist act. Normally where the emergency services respond to the incidents described above they have the responsibility to decontaminate casualties prior to bringing them to emergency departments. These guidelines cover the situations where casualties self present to minor injury units or primary care facilities without being assessed formally for the risk of being contaminated. Recognition of contamination History - patient tells you they were exposed or potentially exposed to a chemical spill / event. Physical signs could include grossly contaminated or wet clothing, noxious odour / off- gassing, upper airway irritation including eye tearing, gross production of nasal secretions, tightness in throat /chest, skin redness and irritation. In situations where the contaminant could be volatile or gassing off the patient may need treatment outside the minor injuries unit and in most of these cases the removal of outer clothing required. Note: turn off any air conditioning systems to prevent smell or air borne contaminate being distributed. Immediate actions confine the movement of the patient to prevent cross contamination of additional staff, patients, and the facility; wear appropriate personal protective equipment and institute the hospital lock down procedure should there be any risk of further casualties. Inform the senior manager in the building or senior manager on call 11

12 Improvised Dry Decontamination Protocol Indication: Urgent clinical assessment or treatment required STEP ACTION COMPLETED 1 Secure an area in which to decontaminate preferably outside 2 Self protect with appropriate Personal Protective Equipment 3 Confirm nature of contamination if caustic or irritant substance (acid or alkali) then see wet decontamination of casualties guidance 4 If patients are walking instruct and supervise self dry decontamination Equipment required; Staff PPE + mask & gloves for patient(s) Yellow infectious waste bags, clear property bag per person Dry absorbent material i.e. kitchen towel, toilet roll, paper tissues blue roll, Towels or clean rags, Strip of blankets or sheets Scissors/trauma shears Blanket or bed sheet for modesty 5 Patient to put on surgical mask (highest protection available i.e. FFP3) and gloves. 6 Remove any contaminated clothing see Disrobing Guidelines below. Ensure patients property goes in clear plastic bag i.e. watch, rings, phones, wallet 7 Expose skin surfaces should now be blotted and lightly rubbed, starting with the face, head and neck and moving down and away from the centre of the body. Change absorbent material regularly 8 Place used absorbent material in a yellow bag separate from the patients clothes 9 Wrap patient in a bed sheet or blanket to maintain modesty/warmth 10 Move patient to isolation area, attend to clinical needs and document 12

13 WET Decontamination Protocol Rinse Wipe - Rinse Indication: Urgent clinical assessment or treatment required STEP ACTION COMPLETED Self protect with appropriate Personal Protective Equipment Secure and move patient to an area for decontamination (preferable external and near drainage or on grass) Assemble equipment (ask someone to do this stay with patient) Staff PPE+ mask & gloves for patient(s) Yellow infectious bags, clear property bag Water, preferably warm 2 buckets or other container (5-10 litre capacity) filled with warm water Detergent liquid soap/washing up liquid add 5ml per litre of water to water in buckets Sponge/soft brush/towel for washing Towels for drying Blanket or bed sheet for modesty Re-confirm nature of contamination is caustic or irritant substance (acid or alkali) if not then revert to dry decontamination method If casualties are walking instruct and supervise self wet decontamination can be done with casualty seated. Remove any contaminated clothing see Disrobing Guidelines below. Ensure patients property goes in clear plastic bag i.e. watch, rings, phones, wallet RINSE the affected areas with clean water NO DETERGENT. RINSE from the highest point downward WIPE using water with detergent added - affected areas with sponge/soft brush. WIPE from the highest point downward RINSE- using water with NO detergent affected areas from the highest point down DRY the skin with a clean dry towel and protect modesty 13

14 REPEAT only if skin contamination remains obvious Disrobing Guidelines The process of disrobing is highly effective at reducing reaction to contamination (including CBRN) when performed within fifteen minutes of exposure. Disrobing is quoted as removing 80%-90% of contamination. If disrobing is followed by appropriate decontamination is done effectively, scientific research has shown that you could be confident of removing the vast majority of skin surface contaminates. Therefore, disrobing must be considered the primary action to be taken to minimise risk and ongoing injury. Disrobing procedure; The patient should 1. Put on gloves 2. Wipe face and then blow nose onto paper towel 3. Put on surgical mask (or highest level mask available) 4. Remove clothing down to underwear, cut off to avoid pulling clothing over the head thus spreading contaminant to eyes and respiratory system. 5. Dispose of clothes and other material to contaminated waste plastic bag, valuables to separate bag if possible then placed in bag with other items 6. Take off facemask and gloves and place in the plastic bag 7. Seal the bag by tying knot or roll up All attempts should be made to disrobe before treatment however a judgement needs to be made about the risk verses the clinical need. 14

16 Patient Contact Template Addition copies should be made if needed Preparation for incidents involving hazardous materials 8 Records of all people involved in your premises must be made and kept. A copy of this list should be made available to the emergency services, Public Health and Occupational Health (for staff). No Family Name First Name Date of Birth DD/MM/YY Address (inc. postcode) Telephone No. GP Name & Surgery Contamination details/symptoms/action Taken 16

17 Additional Information Preparation for an incident involving hazardous material A1 Lockdown The aim of conducting lock down of your building is to control entry to and exit from the building, or to isolate specific area within the building. This should enable you to protect the staff (and patients) already inside, and prevent contamination that has entered your premises from spreading further. Reception areas may become contaminated by the presence of a contaminated patients seeking medical advice, and may, therefore, need to be isolated from other areas of the building. Full lockdown guidance for the NHS is available (Lockdown Guidance protecting your NHS, Security Management Service, February 2009). The range of different buildings utilised for primary and community care facilities varies and it is not possible to create a single template that fits all. Primary and community care managers should conduct individual surveys of their own building and construct simple diagrams or maps to identify: Points of entry and exit Lockable doors Access to keys Staff only areas Usual flow of patients Possible amended patient flows following lockdown PPE requirements Primary and community care practitioners may already have a range of personal protective equipment (PPE) available to them within their work environment. This guidance does not recommend the purchase of additional items, but suggests that a small supply of basic items is made available and accessible to front line primary and community care staff and positioned close to patient reception areas. These may provide a small amount of additional protection where the contaminant in chemically based. The basic PPE that should be available will include: Apron/gowns (splash/waterproof) Gloves Surgical mask Goggles Response Box The term response box is referred to in this guidance. It is meant to indicate an identified and accessible resource for front line primary care or clinic staff. It should be located in a place easily accessible for clinic or practice staff, such as behind the reception area, and should contain items that may be urgently required when an incident involving hazardous materials is suspected. This may include items of PPE, together with: Maps or diagrams previously prepared for the premises Signage provided preferably laminated and with clear instructions for use Action cards provided with this guidance Relevant contact numbers 17

19 Relevant Glossary of Terms A3 Business continuity CBR(N)E Hazardous Materials Isolation Area Self Presenters Worried Well The activity performed by an organisation to ensure that critical business functions will be available to customers, suppliers, regulators and other entities who must have access to those functions. Chemicals, biological agents, Radiation, Nuclear and Explosive contaminants deliberately released as an act of terrorism. These contaminants may be in the form of a mixture to deliberately cause harm or confusion. Also called hazmat can be solid, liquid or gases with the potential to harm people, agriculture or animals. This term is associated with an accidental release of contaminants. A predefined area within a building to separate contaminated or suspected contaminated individuals, to protect those who have not been in contact with contaminant being exposed. Whilst it is indicated this area is inside a building, it may be necessary to evacuate contaminated people into fresh air if the contaminant is giving off gas, very strong fumes or people become symptomatic of being exposed whilst in the area of the isolation area People leaving the scene of an incident before cordons are established by the emergency services. Initially they may not know they have been contaminated until later when they become symptomatic or anxious when they present to health care. It should be noted that they may have travelled some distance from the incident before seeking help. Members of the public who may be near to an incident when it happens, or have heard about it third hand, and who are worried that they have been affected by the incident or consider themselves likely to need medical intervention. It is understood that in a large CBR(N)E incident that the numbers of worried well could be significant.
